(a) Except as otherwise provided by this section, a court acquires continuing, exclusive jurisdiction over the matters provided for by this title in connection with a child on the rendition of a final order.
(b) The following final orders do not create continuing, exclusive jurisdiction in a court:
(1) a voluntary or involuntary dismissal of a suit affecting the parent-child relationship;
(2) in a suit to determine parentage, a final order finding that an alleged or presumed father is not the father of the child, except that the jurisdiction of the court is not affected if the child was subject to the jurisdiction of the court or some other court in a suit affecting the parent-child relationship before the commencement of the suit to adjudicate parentage; and
(3) a final order of adoption, after which a subsequent suit affecting the child must be commenced as though the child had not been the subject of a suit for adoption or any other suit affecting the parent-child relationship before the adoption.
(c) If a court of this state has acquired continuing, exclusive jurisdiction, no other court of this state has jurisdiction of a suit with regard to that child except as provided by this chapter, Section 103.001(b), or Chapter 262.
(d) Unless a final order has been rendered by a court of continuing, exclusive jurisdiction, a subsequent suit shall be commenced as an original proceeding.
